what's this?
RPKI hygiene: C how networks compare →
75.0% of checked blocks have valid RPKI ROA coverage (21 of 28)
Possible discrepancies (3)

These blocks are registered to MMC GmbH but cryptographically authorized for a different, unrelated network (2 distinct holders) — often M&A history, multi-homing, or outsourced/managed hosting, occasionally worth a closer look.

Routed via provider/NREN (2)

These blocks are cryptographically authorized for this organisation's national research & education network or transit provider — expected topology for an institution that routes through it, not a discrepancy.
